aliexpress

[Jonathan]

The lack of any feedback is concerning. Their system works such that the seller only gets your money once you have clicked the button to say you have received the goods and they are satisfactory. If not then you can try to resolve it with the seller. I've placed 22 orders with Aliexpress in the past year and can only find fault with part of one of them. The first item I purchased from aliexpress was two 2200mm long, 20mm TBI linear rails with four bearings for $415 including shipping - I used aliexpress because it was over two years ago, so before they started appearing on eBay and (still) a lot cheaper than elsewhere.

I think it's a pretty safe system, but it's up to you in the end.

Also, don't forget about the customs charges - they will be quite a lot on something of that value.
